Installation failed, reverting ./composer.json to its original content.

我也尝试添加 illuminate/database 但它也显示了同样的问题。

Answer 1

您始终可以在其 composer.json 文件中验证包的要求。

例如，在您的情况下，您可以在此处检查 composer.json: https://github.com/spatie/laravel-sluggable/blob/master/composer.json#L18#L23

你可以注意到这一点:

"require": {
    "php" : ">=7.0.0",
    "illuminate/database": "~5.5.0|~5.6.0|~5.7.0",
    "illuminate/support": "~5.5.0|~5.6.0|~5.7.0"
},

这里说的是最低PHP版本要求，还提到了illuminate/database和illuminate/support包版本要求，即5.5 、5.6 和 5.7 及以上。

这些 illuminate 包适用于 Laravel。它们是 Laravel 框架的核心包，所以它们的版本应该与你的 Laravel 版本相匹配。

您不能在较新的 Laravel 版本上安装旧的 illuminate 包。

我建议您将 Laravel 升级到 5.5 或最新版本。 Spatie 及其软件包大部分时间都是最新的，因此您最好也更新您的软件包。
